To all whom t may concern: y

Be it known that I, TONY Pose, a citizen .0f the United States of America, and a resi- .dent of Aurora, county of Kane, and State of Illinois, have invented certain new and useful Improvements in 'Vehicle-Wheels, oli' which the following is a specitication.

This invention relates in gener-al to 'means for clamping together a pair of circular` members, one .of which is expansible within or without the other member. For example, take a wheel and its tire, the wheel being expansible within the tire for the purpose of clamping the latter thereto.

The main objects of this invention are to provide a wheel having spokes and a hub, with means movably mounted within ,the hub for simultaneously forcing the spokes outward radi-,ally with respect to the wheel hub and thereby .expanding the wheel against its tire; to provide in a device of this class an exp-ansible nut having a conical threaded aperture, and a conical expander adapted to be threaded into said nut; to provide a conical expanding member having threaded engagement with a part of the hub, or a part rigid with the hub of a wheel, whereby the expanding member may be turned with respect to a hub and caused to wedge between the inner ends of the spokes and thus expand the wheel; and to provide a wheel construction which may be quickly assembled or dismantled throughthe agencyvof a conical member adapted to bej''orced between the inner ends of the spokes of the wheel and retained in such position.

An illustrative embodiment of this invention is shown in the accompanying drawings, in which- Figure 1 is a side elevatiompartly in section, of a vehicle wheel constructed according to this invention. Fig. 2 is a sectional view of the wheel taken on the line A-A of Fig. l. Fig. 3 is a detail side elevation ofa wheel expanding device. Fig. e is a `longitudinal sectional view ottheexpandi-ng device. Fig. 5 is a detail of two sectors, a plurality of which form an expanding nut.

This invention is adaptable to purposes analogous tothe specific one here .described and shown in the drawings involving the .clamping of two members, one of which is expansible with respect `to the other, or the invention might be modified to effect a clamping engage-ment between two members by causing one to contract around the other.

It will Aalso be apparent from the following description that the invention is applicable to many dilferent types of vehicle wheels and tires.

ln the drawings the'rim ofV an ordinaryT wagon wheel 1s indicated by the numeral l.

This rim carries the usual metallic tire 2 surrounding its outer edge. The hub 3 otthe wheel'is made in two parts 4 and and' these parts are.clamp-ied vto the inner ends of spokes 6 by bolts 7 passing `through holes .8 in the llangcs 9 and 10 Vof the hub, and elongated slots 11 in the spokes 6. Keyed to the hub 4section 4 by la key 12 is a tube 13 which h-as a right hand thread onl its exteriorsurface. A similar tubeV 14 is keyed to thehub section 45 by a key 15 and the exterior of this tube is provided with a left hand thread. ln engagement with the threads of the tubes 13 and 14 isa threaded memberldhaving a hollow cylindrical aperture 17, as shown in Fig. 4. The walls of the'apei'ture 17 are .opp'ositely threaded from the ends of the menib'er 16 so ,as to coact with the threads on the tubes 13 and ll.V The member' 16 serves as a wheel expanding device and for this purpose is substantially conical in outline, or rather forms a cone frustum provided with a prismatic head 18 whereby it may be engaged and turned byfa wrench. rlhe tapered surface of the expanding device 16 is threaded to engage the interior threads of coacting sectors 19, a plurality of which form an expansible nut with a conical aperture in its center to t the expander 16. rlhe sectors 19 arevslidably mounted with respect to each other by pins 20 tapped therein and slidably fitting in holes 21 ingadjacent sectors. It will thus be seen'that the-` axle 22 is stationary andthat thewheel rotrates around the axle, all of the before men tioned parts, namely, the tubes 13; andl 14.-,- the expander 16, the sectors 19, and remaining parts of thewheel rotating as a unit. .The

.usual nut whichretains the wheel on the vaxle is indicated by the numeral 24.-.

To adjust thenicmber 16 forft'he purpose of expanding the wheel andthereby firmly clamp it to tire 2, itis necessary rstto remove nut 24 and bolts 7 The section 5 vof the hub may then be turned to the right thereby'turning tube 14 and disengaging it from theexpander 16; When the tube-14 the hub. section 5 are removed, the exander 16 b i. means of a Wrench enO'aOin P n .l a :a

the head 18, may be turned inav right hand directionl thereby causing it to travel to 'the left. (Fig. 2) Vwith respect to the wheelV Y and sectors 19 and cause the sectors 19 to Y be spread apart and forced into engagement L with-the inner edges of spokes 6, thereby forcing the spokes outwardly and expand-A ingY thelwh'eel against its tire 2. The sectors 19 in l3`ig. `1 are shown by dotted lines in moved positions as they would appear Y jafteran operation ofthe member 16 as described.

The turning of member 16 may cause it to travel tothe left along tube 13 if this tube iswheld stationary at such time yand provided the thread on the tube 13 is 'the same asthe exterior thread on the ex- -gpandingdevice 16. 1f the tube lvand hub section 4 are permitted to rotate with the expanding device 16 then after the expanding device comes to rest in its desired posi-A Y* l10will engage theV spokes 6 .and the bolts 7 may, again be replaced.

1n the rotation of the wheel with respect vto its axle the expanding member 16K-has Y Ano, tendency to rotate Vrelatively of the'wheel as it is "not in frictional` engagement with ganysta-tionary member, but even accidental rotation'of the member V16 is made impossible by the tubes `13 and 14, because of their respective right and left hand threads engaging the corresponding threads in the interior of member 16. A turning of the expanding. device 16 when the wheel isassembled" lasshown in Fig. 2,' would cause the tubes 13 and 14 to approach each other or move farther apart. The'iirst is impossible because the tubes are substantially in Y contact, andthe second movement is prevented bythe bolts 7 In awheel construction such as the present, k it fis, not necessary to provide special vmeans for fastening tiresto their wheels or inthecase of metallic tires toV shrink them f tained an Vadjiistment of the expanding device. 1.6 when the wheels are4 assembled.

onto the` wheels, as this end may be at- Also' if'any ,f )arts ofthe wheel become v broken the wheel may. be easily disassembled as beforeA described, so that any spoke or' other part may be replaced without requiring skilled handling or any other tools than a wrench. With this device the wooden parts y the member 16 and the interior threads on the sectors 19 are not essential to the operation of the device, as the member 16 may be adjusted Vas required by turning it relatively of the tube 13. A slight adjustment of the expander 16 causes a comparatively considerable change in the length of the circumference of the wheel, and for this reason there need be but slight taper to the member 16 and the aperture formed in the sectors'19.
